Tags: patch

If the point is over a radio button in *eww*, and you press M-s M-w,
then an error is raised with the following backtrace

    Debugger entered--Lisp error: (wrong-type-argument stringp (input ((type . 
"radio") (name . "type") (id . "filter-type-show") (value . "show"))))
      intern-soft((input ((type . "radio") (name . "type") (id . 
"filter-type-show") (value . "show"))) [0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

      funcall-interactively(eww-search-words)
      call-interactively(eww-search-words nil nil)
      command-execute(eww-search-words)

This is easy to reproduce:

    1. M-s M-w yewtu.be/search?q=test RET
    2. Move the point to one of the radio buttons.
    3. Say M-s M-w.

The attached patch fixes the error but maybe the right place to fix it
is in eww-links-at-point?
